Özet
Grain yield is a quantitative trait that a number of characteristics has direct or indirect effects. This research was carried out in 2008-09 growing season with 22 landraces and 3 commercial oat (Avena spp.) cultivars under Kahramanmaras ecological conditions. The research was arranged in a randomized complete block design with 3 replications. In the research, the traits such as stem diameter(SD), flag leaf length (FLL), flag leaf width (FLW), plant height (PH), panicle length (PL), grain filling period (GFP), vegetative period (VP), days to maturity (DM), biomass (B), grain number per panicle (GNP), grain weight per panicle (GWP), thousand kernel weight (TKW) and grain yield (GY) were investigated; the direct and indirect effects of those traits on grain yield were evaluated using Path and correlation analysis. According to Path analysis, GFP (47.74%), VP (39.41%), B (31.15%), GNP (29.80%) and TKW (24.78%) had the highest direct effect on grain yield. Based on correlation analysis there was a positive and significant relationship between grain yield and stem diameter (r = 0.480**), flag leaf length (r = 0.230*), flag leaf width (r = 0.241*), grain filling period (r = 0.224*), days to maturity (r = 0.339**) and biomass (r = 0.313**) while a negative and significant correlation found with plant height (r = -0.315**). In the study, Path analysis and correlation coefficients used to determine direct and indirect effects of some agronomic traits on grain yield showed that GFP, VP, B, GNP and GWP might be used as a selection criteria for grain yield successfully.
